ABSTRACT
The science of securing a data by encryption is Cryptography whereas the method of hiding secret messages in other messages is Steganography, so that the secret’s very existence is concealed. The term ‘Steganography’ describes the method of hiding cognitive content in another medium to avoid detection by the intruders. This paper introduces two new methods wherein cryptography and steganography are combined to encrypt the data as well as to hide the encrypted data in another medium so the fact that a message being sent is concealed. One of the methods shows how to secure the image by converting it into cipher text by S-DES algorithm using a secret key and conceal this text in another image by steganographic method. Another method shows a new way of hiding an image in another image by encrypting the image directly by S-DES algorithm using a key image and the data obtained is concealed in another image. The proposed method prevents the possibilities of steganalysis also.

ONTENT BASED IMAGE RETRIEVAL USING COLOR AND TEXTURE
Manimala
ABSTRACT
Singha and K.HemachandranDept. of Computer Science, Assam University, Silchar India. Pin code788011
The increased need of content based image retrieval technique can be found in a number of different domains such as Data Mining, Education, Medical Imaging, Crime Prevention, Weather forecasting, Remote Sensing and Management of Earth Resources. This paper presents the content based image retrieval, using features like texture and color, called WBCHIR (Wavelet Based Color Histogram Image Retrieval).The texture and color features are extracted through wavelet transformation and color histogram and the combination of these features is robust to scaling and translation of objects in an image. The proposed system has demonstrated a promising and faster retrieval method on a WANG image database containing 1000 general-purpose color images. The performance has been evaluated by comparing with the existing systems in the literature.

ABSTRACT
Tuberculosis (TB) is very dangerous and rapidly spread disease in the world. In the investigating cases for suspected tuberculosis (TB), chest radiography is not only the key techniques of diagnosis based on the medical imaging but also the diagnostic radiology. So, Computer aided diagnosis (CAD) has been popular and many researchers are interested in this research areas and different approaches have been proposed for the TB detection and lung decease classification. In this paper, the medical background history of TB decease in chest X-rays and a survey of the various approaches in TB detection and classification are presented. The literature in the related methods is surveyed papers in this research area until now 2014.

ABSTRACT
Sindhi language is primarily spoken in the Sindh province of Pakistan, and in some parts of India. Languages phonemic inventory include vowels, consonants and diphthongs. This paper presents acoustic analysis and properties of the glide consonants of Sindhi. Glides are considered having stable and predictable formant structure and associated acoustic properties like vowels and diphthongs. Understanding the corresponding acoustic similarities, differences and relationship between three types of these sounds is the subject of discussion of this paper.

ABSTRACT
The main objective of this paper is to elaborate how defective fabric parts can be processed using Matlab with image processing techniques. In developing countries like India especially in Tamilnadu, Tirupur the Knitwear capital of the country in three decades yields a major income for the country. The city also employs either directly or indirectly more than 3 lakhs of people and earns almost an income of 12, 000 crores per annum for the country in past three decades [2]. To upgrade this process the fabrics when processed in textiles the fault present on the fabrics can be identified using Matlab with Image processing techniques. This image processing technique is done using Matlab 7.3 and for the taken image, Noise Filtering, Histogram and Thresholding techniques are applied for the image and the output is obtained in this paper. This research thus implements a textile defect detector with system vision methodology in image processing.
Keywords:
Imageprocessing, Matlab 7.3, Gray image, Histogram, Thresholding.

ABSTRACT
Classification of gender from fingerprints is one of the important steps in forensic anthropology. This forensic anthropology is used to identify the gender of a criminal in order to minimize the suspects list of search. A very few researcher have worked on gender classification using fingerprints and have gain the competitive results. In this work we are trying to fuse the fingerprint and age biometrics for gender classification. The real fingerprints were collected from different age groups such as 15-20 years and 2060 years of the rural and urban people. According to this experimental observation soft biometric information can be used significantly to improve the recognition performance of biometric system. The overall performance of the proposed method is found to be satisfactory and more competitive.

ABSTRACT:
In this paper, we discuss test data compression and decompression method based on variable length Golomb codes and 2-V Golomb Codes for test data. The method is targeted to minimize the amount of test data, which reduces the size of memory required in ATE for test data and also time required to transfer test data to specific device on SOC. We completed MATLAB coding for both methods and applied test vectors of some standard ISCAS benchmark circuits and compared results for same. Experimental results on ISCAS benchmark circuits show that the compressed data produced by 2-V Golomb coding is better than Golomb Coding method.
KEYWORDS:
Automatic test equipment (ATE), precomputed test sets, variable-to-variable-length codes, Golomb coding, RLE, SOC, Golomb Coding, 2-V Golomb Coding.

ABSTRACT
Noise is always presents in digital images during image acquisition, coding, transmission, and processing steps. Noise is very difficult to remove it from the digital images without the prior knowledge of noise model. That is why, review of noise models are essential in the study of image denoising techniques. In this paper, we express a brief overview of various noise models. These noise models can be selected by analysis of their origin. In this way, we present a complete and quantitative analysis of noise models available in digital images.
